HI9146 / HI 9146 Portable Dissolved Oxygen Meter / DO Meter

The HI9146 is a rugged, portable dissolved oxygen (DO) meter designed to provide laboratory precision and accuracy under harsh environmental and industrial conditions.
Developed for dissolved oxygen and temperature measurement in water, wastewater, and environmental testing, this meter can also compensate for altitude and salinity.
Robust waterproof casing makes it ideal for field use.
Setup and calibrate your meter in no time with 1 point calibration.
Perfect for water and wastewater monitoring, environmental, and aquaculture applications.
